Background

Nisha had a rough childhood, having to deal with an abusive mother who often yelled and tossed all sorts of things at her. She uses this as exercise to train her reflexes, practicing until she got good at catching anything her mother throws at her. One day, Nisha's father got her a puppy, which she started to care for. The two of them were inseparable, until the dog was bitten by a frenzycrutch. At first, the dog showed no strange signs, but during one night, while Nisha was catching things her mother throws at her again, one of them slipped off her hand and hit the dog. Its eyes went red, lips went blue, and it jumped on Nisha and bit her in the neck. After getting patched up by her father, she used a shovel and bashed the dog's brains out.

Involvement

As Nisha grew, she began to develop an interest in killing bandits. She became known as "the bandit who kills bandits", an occupation which she finds fun. Her actions eventually caught the attention of a man named Jack, who then recruited her to be part of his team of Vault Hunters. She then joined three other Vault Hunters: Athena, Wilhelm, and Claptrap, on a spaceship headed for Helios, Hyperion's moon base.

After finishing her job, Nisha began a romantic relationship with Handsome Jack, and became his significant other. Nisha was involved in the fall of New Haven and was the one who captured and imprisoned Brick, after killing his beloved puppy. At some point, she was given free reign over a large tract of the planet Pandora, and governs Lynchwood as its Sheriff with an iron fist, with each of her more than 200 laws punishable by death. After the Vault Hunters arrive and start disrupting her control, she challenges them to a showdown.
